PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,018, dated March14, 1882.

Application filed November-2,1881. (No model.) Iatcntedin AustriaSeptember 18,1880.

To all whom it may concern: 7

Be it known that I, CONRAD PRUNER, a citizen of the Empire of Austria,residing at Wiener-Neustadt, Austria, have invented new and usefulImprovements in Paper-Box Machines, of which the following is aspecification.

The object of my invention is to produce antomatically boxes or tubesfrom paper, pasteboard, or similar material by means of asuitably-arranged machine. The machine con" structed for this purposetakes the material employed for the production of the boxes or tubesfrom a roll, prints it on any desired place, pastes the seams, cuts it,and folds the cut material into the desired shape. When matchboxes areto be made it' applies paste to their bottom, covers it with sand, (thusforming the friction-surface,) and finally drops the so-finished box. Inmaking other boxes or matchbox covers the sanding apparatus may ofcourse be omitted, as well as the printing ap paratus, if so desired.

This invention is illustrated in the accompanying drawings, in whichFigure 1 represents a side elevation of the machine. Fig. 2 is a plan'of the same. Fig, 3 is a sectional elevation, the line or a Fig. 1,indicating the plane of section andlooking in the direction of the arrowopposite to that line. Fig. 4; shows the lever arrangement for actuatingthe cutters in a view corresponding to Fig. 1. Fig. 5 is a side View ofthe former-disk. Fig. 6 is a plan of the same. Fig. 7 is a section inthe plane :10 m, Fig. 5. Fig. 7 is a section in the plane a: l Fig. 5;Figs. 8 and 9, side view and plan of the paste-roller for the boxes;Figs. 10 and 11, the same for the box-covers; Fig. 12, section on theline y y, looking in direction of arrow Y in'Fig. 2, showing themechanism for the. movable folders; Figs. 13 and 14.,s'ide view and planof the pasting apparatus; Figs. 15 and l6,front and side view of aformer and slide; Figs. 17 and 18, front and side view of springcounter-slide for pushing the formerslides toward the circumference ofthe formerdisk; Figs. 19 to 27, the different folders for bottom andside flaps of the boxesin different views. Fig. 28 shows the form of aboxblank ready cut. The shaded parts indicate the places where the pasteis to be applied. Figs. 29 to 32 are perspective views of the box in thedifferent stages of manufacture. Fig. 33 shows a finished box, and Fig.34 a finished cover for such box.

Similar letters indicate corresponding parts.

The machine operates in the following manner: The material taken from aroll, a, passes over guideroll I) through a printingapparatus, c,whichprints a label, mark, or any design upon it. Then it passes to thepaste-applying roller (1, supplied by rollerf with paste taken fromreservoire. Rollerd,beingsuitably formed for this purpose, as shown inFigs. 8 to 11, applies paste to the box-blank on the proper places wherethejoints are to be formed. Upon reaching disk 9 the blank-strip, whichis some- I what broader than the mandrel or former, is

held by former it while cutters i and m make the required incisions forforming the bottom flaps. These incisions only penetrate in that part ofthe blank which serves to form the bottom of the box, and which part,while being thus cut, rests upon a circular plate, l, con nected withthe cutting apparatus k, Fig. 3.

Knife m cuts across the entire width of the material, thus dividing theendless strip into blanks of the required length. A blahk'thu's preparedisshown in Fig. 28 on an enlarged scale, the full lines showing theincisions made by the knives,while the dotted lines indicate where theblank is to be bent in order to form the box.Arrivingatn,Fig.l,theformer-slidcand former, and with the latter thebox-blank, are by the action of a pin, h, which is guided in anirregular eccentric groove in the stationary disk or plate 0, drawn intothe corresponding recess of first motion the blank has received the formshown in Fig. 29. An arm, p, (folder,) moved -b eccentric andleverdevice Fi s.2and

Thediskg moving on farther, the second (lower) bottom flap,

III, Fig. 31, of the box is turned down by folderr' and the secondpasted side'parhIV, Fig.31,by

folders. The oblique folder t turns down the third,V, Fig. 31, andfolder to the last bottom flap,Vl, Fig. 33. The last-mentioned fourfolders are fast to the frame of the machine, and have to each other andto disk 9 the position shown in Figs. 5 and 6. For the betterillustration of their different forms, the folders are shown separatelyrin Figs. 23 and 25, s in Figs. 19 and 20, tin Figs. 21 and 22, and u inFigs. 26 and 27. Pin h, sliding in the eccentric groove of stationarydisk 0, Fig. 1, pushes the former-slide outward past a verticalpasteroller, w, supplied by roller 00 with past or gluetaken fromcistern y. Paste is applied to the bottom of the box by said roller w.When glucis the adhesive material to be used, a lamp, y, is placedbeneath the cistern y in order to keep the'same in a fluid state. Thesanding apparatus 22, through the orifice o from which sand iscontinually flowing while the machine is in motion, sprinkles sand uponthe glue or paste covered bottoms of the passing boxes or tubes to formthe friction-surface for matches when the boxes are to be used for thispurpose. Pin orcrutehzoftheformerlaengagingwith and following the curveof guideway a 1), draws the former out sidewise from its slide,causingthe finished box or tube shown in Fig. 33 to drop off. When thebox has been removed and the former, by the continued rotation of disk9, arrives at the place where the strip of material touches thecircumference of said disk g, the former is moved into its slide againbycrutch z engaging with'and moving along the upper guide-bar, g d,seizes the paper, draws it underneath the cutters, and so on, theprocess just described being repeated.

The machine shown, for example, in the annexed drawings is provided withtwo formerdisks, each having a'suitable number offormers and the devicesappertaining to them. The object ofhaving two disks is mainly, in makingmatch-boxes, to form upon one disk the boxes, and simultaneously andconsequently in like numbers the covers or caps on the others.Coversorcapsgenerallyrequiringneitherlabelprint nor sand, the printing,bottom-pasting, and sanding devices have been omitted on that side wherethey are made. The ma'teiial for caps or covers is here taken from'theroll a, fed by one or two guide-rollers, 1 2, under thepasteroller, fromthere to the former-disk, and has only to pass the cutters and foldersin order to be dropped as a finished cap (shown in Fig.

34) in the same manner as the box.

For the reception of the former-slides and their spring counter-slides,disk 9 is provided with a corresponding numberof recesses or radialslots, as shown in Figs. 5 and 7. Plates g, having the form of segmentsof a circle, are screwed on the sides of disk 9, so as to securely guidethe former-slides and to keep them in their places.

Figs. 15 and 16 show the former and slidein front and side view, thedotted lines indicating the position of the former when drawn aside.Disk g is mounted upon shaft 3, and

receives motion by gearing 4 through crank or pulley 5. A pin orstud,h', fastened to the slide fits into the irregularly-curved slot orgroove, Fig. 1, of stationary disk 0, and, following its course duringthe rotary motion of the disk g, causes the former slides to be drawn inor pushed out.

To prevent the outer edge of the former, when its slide is drawn intothe disk, from moving in beyond the circumference of said disk, thespring counter-slide k is used, the exterior end of which is bent atright angles,the bent part reaching underneath the former. Spring hcontinually tends to push this counter-slide outward toward thecircumference of the disk. When, by continued rotation of the disk 9,the former-slide arrives in its lowest position with reference to themachine, the former being drawn out sidewise leaves the disk entirely,and the action of the countersliile h ceases by the shoulder h coming incontact with ring 7r", fastened to disk g, which prevents it. (the slideh from coming out beyond the circumference of the disk. The main objectof this spring counter-slide is to press the former against folder 8,when it (the former) is passing, in order to insure a better joining ofthe sides of the box or tube.

The cutting apparatus (best seen in Fig. 4) consists of along knife orcutter, m, preferably serrated, for cutting the material across itsentire width, and of four or five short cutters or knives, i, for makingthe incisions for the bottom flaps. All of these cutters are adjustablyfastened by nuts or otherwise upon a shaft, 70. This shaft turns injournals k resting upon plates fastened onto upright k Plates k alsosupport the circular plate 1, upon which, projecting over theside of thedisk, rests while being cut that part of the blank which is to form thebottom of the box. Motion is imparted to the cutters 'i and m by thelever arrangement 70 and 7c in the following manner: 0am [612, Fig. 4,turning in the direction indicated by the arrow, acts on the slidinghead k, moving the same to the left, thereby drawing the connecting-rod7c and lever is which latter, through the shaft 70 raises lever 70, andas the latter is attached to the rod k whichconnectsthe levers h thelatter will be elevated, thereby raising the levers k which effect therock ng of the shafts It? in theirjournal bearings or supports k so thatthe knives t and mare depressed or lowered to perform the cuttingoperation. When the lift of cam k recedes from head 70'" levers 70 7care free to return by their own weight to their old position, thuslifting the cutters up again. Should the weight of the lifting-leversnot suffice to move them back, there is for this purpose a pin, 70',fastened to the side of cam is" in such manner as, on turning aroundwith the cam, to engage with another pin, 70 fast to the sliding fork ofhead 70', and so to draw the latter back, moving the levers and raisingthe knives. A vertical red, 70 movably connected on its IIO lower end.with the extension of lever k and guided above by an. upright, It,limits the downward motion of the cutter-actuating lever by its nut 76touching upon upright It.

When the machine is in operation the disk 9 has a continuous rotarymotion, and as the cutting of the paper or other material requires acertain space of time, a tearing of the material would be theconsequence if the cutters respectivel y of the whole cutting apparatusdid not partake of the forward circular motion of the disk. To permitthe apparatus making this circular motion along with the disk, the wholeis, by upright 76, movably mounted upon main shaft 3. Catches h, Fig. 1,are fastened to disk g, so as to engage with the lever of.

cutter at when it descends to make a out, carrying the whole cuttingapparatus along, turning upon its axis 3. After the out has been madethe knives are raised, lever m is disengaged from catchh, and by rod 7:being acted upon by spring It. the whole cutting apless roll of materialinto a number of strips ofv paratus is swung back into its originalposition; and at every fresh cutthis proceeding is repeated.

Fig.2 shows a plan, and Fig. 12 a side view,

of the device for operating leverp. Motion is imparted by eccentric (1upon shaft g. In this case, where two former-disks are used for thepurpose already mentioned, two levers, p, are of course required, and inorder to raise and lower them simultaneously and uniformly they areconnected with each other by straps g and The sanding apparatus '0,Figs. 1 and 3, consists of a box or casing fastened to a plate, Q1 inwhich box turnsabucket-wheel, v The apparatus works automatically in thefollowing manner: 0n turning the shaftv upon the end of which,reachinginto the sandbox, the bucket-wheel is fast, the latter alsorevolves. The buckets, dipping up the sand which had previously beenpoured into the box through funnel 12 deliver it on reaching the topinto funnel 11 from where it runs outthrough orifice r, and there coversthe bottoms of the boxes as they pass. The superfluoussand runs throughfunnel v buck into the box, to be dipped up again. The bucket-wheelshaft receives motion from shaft 61 by pulley o and d. d is the shaft ofthe pasteroller d.

For printingthe box-blanks any kind ofpress may be used and be operatedby suitable gearmg. i

All parts and devices abovedcscribed are so connected with each otherthat all may be driven by a single crank or pulley,as shown in thedrawings.

The blank-strips for the boxes or tubes to be made are obtained bycutting up a broad endthe required breadth.

In conclusion it must be remarked that the machine herein described maybe used for making boxes or tubes ofany size and almost any shape bysimply exchanging the formerdisks, formers, and paste-rollers for otherscorresponding to the desired shape and size.
